PRINTING DEVICE.

l J To (17/ trim/ll 1'2 )lu/ concern.

Be itknown that I, \VnLLmo'rox FRANCIS llnanmrr, a citizen of the UnitedStates, residing at Akron, in the county of Summit and State of Ohio,have invented new and useful Improvements in Printing Devices, of whichthe following is a specification.

This invention relates to improvements in printing devices and has forits object the provision of means especially adapted to producing wavylines on paper for furnishing a back-ground on which may be formeddesigns such as mottling or a moire etl'ect although the invention isnot limited to producing any particular formation of lines.

The invention. contemplates the provision of means which will ftllcflthe paper to be printed against an inked surface with varying degrees ofintensity at different points so as to produce heavy shadows or iadedportions tapering or becoming less intense with gr at accuracy andsmoothness to produce beautiful even effects not heretofore capable ofbeing produced. I accomplish this result by means of a sheet of materialconstituting a base on which are mounted a plurality of projections ofresilient material, usually rubber, having the base portions thereoflarger than the projecting portions or the apiccs so that the portionsof the paper which are pressed forward by the apices or the projectionswill receive a greater supply of ink from the ink-plate than thoseportions which are pressed more lightly by the sides of the projectionwhich receive a constantly decreasing amount of ink so as to produce ashaded effect.

F urther the invention contemplates the use of my improved device forpressing the opposite sideof a paper against the inked surface forproducing the shaded efi'ects as contradistinguished from inking thedevice itself and passing the same over the paper, so that at all timesthe device is free from contact with ink.

With the foregoing and other objects in view. the invention consists inthe novel con struction, combination and arrangement of partsconstituting the invention to be here 'inafter specifically describedand illustrated in the accompanying drawings which form a part hereofwherein is shown the preferred embodiment of the invention, but it is tobe understood that changes, variations and modifications can be resortedto which come Specification of Letters Patent.

In the drawings in which similar reference numerals indicate like partsin the different figures, Figure l, is a sectional view of a portion ofa printing press showing my device in operative relation therewith;

lfig. 1s a perspective view of a small portron of my improved device;and, Fig. 3, is a small piece of printed matter showing the results ofthe use of my improved device..

In the drawings the reference numeral 1 denotes an ordinary printingcylinder provided with a feed-table '2 and carrying dogs or catches 3and having a guide 4 all of ordinary construction. 1 is a reciprocatingmember 5 a portion (3 of,

which constitutes an inked surface whicl} can be inked through themedium of an in] roller 7. The portion 6 is a substantially plainsurface in contradistinction to a surface which may be formed by type orother parts adapted to themselves provide a design upon the sheet to beprinted.

Mounted on the cylinder 1 and held in position by means of the dogs orcatches 3 is a sheet 8 of suitable material usually metal, on which aresecured by cement or other wise, a plurality of projecting members 9shown in the drawings as parallelstrips, segment-shaped incross-section, and preferably formed of The configuration of the strips9 immaterial but said strips should be provided with enlargedbase-portions where they are fastened to the plate 8 and shouldgradually taper toward their outer portions which engage the paper.

In use, the paper 10 is fedover the table 2 and is ressed against theink surface 6 by means of thenzembersi), the degree of pressure beingregulated as is usual in the printing art and the result is that thereis produced on the paper an'impression or marks corresponding in contourtothe 0011-; t'ormation'of the strips 9 and consisting of deep central,portions 11 from which the color gradually shades off to the points 12and usually at oints midway between the marks 11 themes little or nocolor applied to the paper.

As will be understood, the surface 6, being substantially plain andtherefore having a comparatively thin ink coating, will, when the sheetis forced in contact therewith by the strips 9, notv place a solid coloron the' sheet throughout its face, but the varying 'degrees of pressurewill cause a greater or less amount of ink to be taken up by the videdwhen the cylinder carries the sheet over the inked surface.

In use it is customary'to'make first of i all alight impression bypassing the paper through the printing press and drying the same afterwhich the paper is again subject-- ed to the press and the colordeepened and rendered more uniform by the superimposition on theprevious printed surface of a relatively thin transparent color orcoating arranged to coat approximately the entire surface with theresult that the lines or im' pression originally placed on the paper bythe first impression will appear deepened or having greater intensity ofcolor than the other portions which are less intensely printed, and thewhole blended and covered by the superimposed transparent coating,

so that there will be imparted to the fin-, ished article a wavy ormoire effect with,

the entire surface completely covered, ex-
